amplitudes_2Pi/ampli [ Subroutines ]

[ Top ] [ amplitudes_2Pi ] [ Subroutines ]

NAME

subroutine ampli(r,q,p1,p2,p4,p5,o,t,betaToLRF,mediumAtPosition)

PURPOSE

Calculates the 2pi photoproduction amplitude taken from Nacher et. al. NPA 695 (2001) 295. t is given in the CM frame, only transverse components are calculated.
